Question: What is the equivalent Chinese standard material for A335 GR.P11? For welding A335 GR.P11 SMLS steel pipes, what welding wire and electrodes should be used?
A335 GR.P11 is equivalent to the Chinese standard material 12Cr1MoV. For welding A335 GR.P11 SMLS steel pipes, it is recommended to use ER80S-B2 wire or E8018-B2 electrode for welding. These welding materials exhibit good weldability and compatible mechanical properties with steel pipes made of 12Cr1MoV material. During the welding process, please follow the appropriate welding procedures and process parameters to ensure the quality and performance of the welds. .
Foreign welding wire ER80S-B2, welding rod E8018-B2. Domestically, it is as follows.
